NEW areas of Donegal highlighting “anomolous” gold concentrations in stream sediments have been identified in the most comprehensive mapping project undertaken in the border counties to date.
The Tellus Project, which commenced in July 2011, involved an extensive airborne geophysical and ground-based geochemical survey covering the six border counties of Donegal, Sligo, Leitrim, Cavan, Monaghan and Louth.
As well as highlighting known existing gold occurrences in Donegal, such as Glentogher and Glencolmcille, a number of new areas with anomalous gold concentrations have been identified including several areas of the Inishowen Peninsula, and Termon.
A final stand out result is the survey’s contribution to the accuracy of maps showing areas with naturally high levels of radon.
Working in conjunction with the Radiological Protection Institute of Ireland, the new data has helped improve, by a factor of ten, the accuracy of maps, allowing for high radon risk areas to be targeted for further investigation and ultimately the protection of public health.
Along with previously known high radon risk areas in Sligo, new areas of potential risk were identified in parts of Donegal.
The survey results are available, free of charge to everyone, to view and download from the Tellus Border website www.tellusborder.eu
